The mainpurpose of my invention herein disclosed is to provide a multiple-magazine machine in which the magazines are of simple construction and adequate capacity and may be readily moved to and from operative position for selective use. Incidentally, l provide certain distributor improvements, keyboard improvements, and other minor and contributing improvements to co-operatewith the magazine system, all of which will be fully explained as the de.- scription progresses.

Fig. 12 is a view on the line 12-12 of Fig. 10. Y f* `Magazz'ne .s'ystem.-As shown in the `drawings, the magazines A are tive in number, but a greater or smaller number may be employed to meet various requirements. The magazines are as usual provided with opposedgroove channels in which the matrices' are stored in columns according to character. The magazines are shiitable in the manner of U. S. Patent No. 1,136,569 (April 20,

1915), but in the present instance as distinguished from said patent, the magazines differ one from another as to the number and spacing 01"' their channels, and means is provided Jfor releasing the matrices from the magazines as thus differentiated and are, divided midway ot' their width (Fig. 3), hence there are two columns or stacks of magazineV halves, one column being supported on a lett-hand trame B and the other column on a right-hand iframel C.l These frames are ly spacing apart the magazine 'dire-ct supports B. AAdditional rigidity for the frames is obtained by means of spacing rods R, R1,

R2. .A central iframe member K provides additional support for the rock-shaft D and is shaped to receive and guide' theparallel portions of the magazine supports B and C, the sides of which bear against suitable antifriction rollers L and M. Similarly, the torward surfacesot the frames B bear against anti-friction rollers N. Tie-rods O brace the central frame member K tronia coluinn-like portion P of the machine trame, The lower extensions of the movable supports B, C are guided between the rock-shaft D and guiding plates El secured to opposite sides of the main trame E. As lthus supported the two columns of magazine halves have a reciprocating movementin parallel paths when the supporting shaft D is rocked. When the magazine halves are in position mid-way of their possible movement, as in Fig. 2, the 1 middle magazinez indicates operative position, Vhence any pair of magazine halves brought to such position become the operative magazine. For example, the top magazine-half of one column is the mate of th'e bottom magazine-half of the other column when the two halves are brought to opera-V reference character A in Fig. 3 indicate how the magazine halves match when shifted toV operative position. 'The halves l-Q-S reading downward from the center of the y left-hand stack match successively the 'halves 1-2-3 reading upward from the center of the right-hand stack; the same is true of the halves l-4-3 reading inan opposite direction in the vrespective stacks. Y 5

Each magazine-half is provided with front and rear cross bars S on top and similar bars T beneath, therebeing a tongueand-grooveI connection between the bars on top of one magazine and those beneath the magazine next above. The ends of the bars rI` project beyond the edge of the magazine to which they are secured and reston shouldersU formed in the supporting frames B, C. Top magazine-s of each column have a similar tongue-and-groove engagement with the horizontal arms of right-angled levers V which are pivoted on a shaft IV and are capable of a slight movement under control of cams X on opposite ends of a shaft Y bearing in the frames B or C. lVhen these cams Vare turned by moving a handle Z outwardly as at the right of Fig. 3, the horizontal arm of the levers V is .thereby tilted and lifts first the top magazine and theneach succeeding magazine according to the extent ofmovement of the camsv X, each magazine being suspended from the one next above by'reason of the tongue-and-groove connection described. The lower most magazine thus suspended is freed of the weight of the magazines thereabove and may therefore be moved edgewise toy or from its column position, as shown in dotted lines in Fig. 3. ABy shiftingthe supporting'frames to the appropriate position any magazinehalfV may be thus removed to a position above and resting upon the opposite magazine column and then lifted from the machine and another magazine substituted therefor. By reversing the position'of the tilt-frame the other half of the magazine may be similarly removed from its column. n As a means for holding the magazine columns in any selected operative or removal position, I secure to the end of the rockshaft D asegmental rim D1 having a seriesy of positioning notches D2 any one of which notches may be brought to a position above selected for use.

the rock-shaft and there engaged by a latching rod D3. At its lower end this latching rod is confined in a groove D4 and is movable longitudinally for the purpose of locking or freeing the notched rim D1. The latching rod D3 is additionally guided in an lextension K1 of the central frame K. Itis pair of swinging brackets D8, the furtherV functions of which is hereinafter explained. rFhe brackets D8 are pivotally secured to the assembler entrance throat Q (Fig. l) by means 'of hinge pins Q1 and when swung outwardly as swung in broken lines in Fig. 1 the latching rod D3 is thereby forced downward and the rim D1 may turn through the clearance notch D5 and Vwith lthe return movement of the rod V Dbe latched in a selected posit-ion according to the'magazine The lowermost notches D2 are for use when moving the bottom magazine of one column to a position above the top magazine of the other column, for the purpose of removing the magazine as eX- plained. The manner of controlling the movement of the magazine columns between one and another locked position is hereinafter explained. y

K @g1/board .ansieht-The magazines A are intended to diifer one ,from 'another in regard to the number of their channels. For

example, a magazine intendedfor large matrices such as d-pointmay have only channels; a magazinefor 1S point matrices may have channels,landV a magazine for very small matrices may have 120, channels. Hence it is desirable that there be associated with each magazine when in use a keyboard having keys equal in number to the channels in the magazine in use. IVith this purpose in view, Iprovide four keyboards (l, 2, 3, 4) mounted in common endvmembers 5 rotatable with a shaft 6 for the purpose of moving a selected keyboard to operative position. The shaft 6 bears at opposite sides of thekeyboard group in side arms l() secured to a pivot shaft 1l with a bearing in the. machine base F. When in normal position the keyboards cannot be rotated because rof the interfering escapement reeds 20. i It is therefore necessary to lower the keyboards as shown in dotted lines in Fig. '1 before they can be rotated. `For the purpose of such movement to and from normal position they are balanced by means of a compressionV spring I3 held in position on a rod 14 havmg abearing in a vertical angle-portion For the purpose of such movement lill? iso A 102t of the side arm 10, and slidabletherein when the spring is compressed. lThe other end of the spring rod is secured by means of av link 16 inra projection 17 from the side' of an arm 18 pivoted with a shaft 15 bearing in the machine frame E. The arm 18 and the arm 10 are spaced apart by the link 16, and the relative positions of the pivotal points of these two arms is such that when they are lowered to the position shown in dotted lines the spring 13 is compressed and supports the weight of the keyboard group in common with two additional springs 19 and 21. The tension of the nsprings 19 and 21 may be regulated by means of a sleeve 22 on the'spring rod D7, the sleeve being threaded into the cross lnember DG hereinbefore described. The springs 19 and 21 may be in duplicate at opposite sides of the machine and are so shown in Fig. 2.` The brackets D8 carry arms D9 which supportl a keyboard tray 23 and copyholder 24. WVhen the keyboards .are in normal position a latch 25` carried by the arm 18 vengages a notch in the right-hand arm D9 and thus holds the keyboards in position.l Before they may be loweredA the keyboard tray 23 must be'swung out as illustrated and ythis movement slightly compresses the spring 19 against an eye-bolt 24 carried by the arm 18, thus starting the downward movement of the keyboard group regardless of the stronger spring 13; when the tray 23 is returned to normal position the tension of the spring 19 is gradually lessened and the stronger spring 13 raises the keyboard group and the latch 25 enters its notch. The spring rod D7 slides in the eyebolt :Zland asthe tension of the spring 19 increases, that of the spring 21 decreases, with the condition reversed as the keyboards rise.

Associated with each keyboard is a projecting stud 26, and when the. keyboards are in normal position one of these studs engages a notch 27 in the end of the arm 18,

Y thus preventing any rotary movement of the keyboards. As the keyboards are lowered the stud 26 graduallyrecedes from the notch 27 and when entirely free thereofthe group of keyboards may be rotated to bring a selected one to operative position. VThe return movement of the group then causes another stud 26 to enter the notch 27.

Vvlhen the keyboards are rotated a gear 7 on the shaft 6 moves a Centrally pivoted arm 8 about its pivot 9, the direction vof this movement depending on the direction in which the keyboards are rotated.

Inter-control between magasine System ma? key/50am? system-In order that a key-V board having a given number of keys may be brought to operative position in time with a. magazine having a corresponding number of channels, I provide as follows: A connecting rod 28 is vhinge-connected at its upper end vwith the shaftv W and at its lower end is .hinge-connected with the centrally-pivoted arm 8 at a point central with the pivot. point 11 of the keyboard arm 10; therefore when the keyboard system is lowered, no movement is imparted to the connecting rod .28. But when the keyboards are rotated the gear 7 arm 8 and causes the. magazine columns to move a` related'distance inv a' direction depending on the direction of rotation of theV keyboards.v For example, ifv the keyboards 1 and 3 have 120 keys and (in the righthand stack) the middle magazine A1, to

magazine A3 and bottom magazine A3 eac have 120 channels, a 180-degree rotation of the keyboards from the position shown in Figpl, will in one direction cause theV lower magazine A3 to move to operative position in time with the keyboard 3; and rotation in the other` direction will move the top magazine A3 to operativeposition in time with the same'4 keyboard 3. It will be apparent that if these three magazinesA each havefthe same number of channels two keyboards having the same number of keys are required for automatically timing the movement ofthe magazines and keyboards. But the vduplicate keyboard 3 may be dispensed. w-ith and the same result obtained by manually moving the lower end of the connecting rod 28 to an appropriate perforation 29 in the arm 8, thus moving the magazines without rotating the keyboards. In suchcase'the end of the rod 28 passes through the selected perforation 29 a sufficient distance to enter a registering perforation in the arm 10, thus securely locking the parts together regardless of any looseness between the gear 6 and the toothedY end of the arm 8.V Likewise, if a keyboard 2 has 90 vkeys and a magazine in the position A2 has a corresponding number of channels, movement 'of thekeyboard 2 to operative position will move the magazine tov correspond; and in similar mannerthe magazine in the position A3 will move to operative position in time with the keyboard 3. Each time the keyboards are raised to operative position following movement ofthe magazines, the locking rod D3 engages an appropriate notch D2 in the locking member D1, 'as hereinbefore explained. The perforations 29 are so arranged that, regardless of the position of the arm 8, one row of the perforations will register with .a perforation in the arm'lO; hence, regardless of the number of keyboards, and regardless of which keyboard is in use, a magazine in any position in its moves the segmentlill? column maybe manually brought to oper- Y ative position without rotating the keyboards, provided thenumber ofkeys corresponds with the number of channels; but it is always necessary to swing the tray 23 forward in 'order to move the latching rod'I)3 so that the magazines may be moved, whether directehianually or otherwise.

The` escapement actuating reeds 20 are equal in number to the maximum number ofA channels in a magazine and the correspond- 'ing number ofkeys on a keyboard, and when a notches 30 in a plate 31 fitting in grooves 32 in the facing sides of the brackets D8. In the proportion selected for'illustration each fourthnotch (30a) is deeper than the remaining notches. When employing the reeds ill-reduced number, every fourth reed is moved forward into its notch to a non-operative `position in front of the escapements 33. F or this and other purposes the reeds are offset as at 20"L and their upper ends 20" are guided in notches .34 in a plate 35, except that every fourth reed is guided in al pe-rforation 36. This plate 35 is supported on posts 36 ksecured near opposite ends of the lower plate 31. Outside of each post 36 an arm 37 is securedto a shaft 38 mounted in the posts 36. A keeperplate 39 engages a groove 40 in the plate 35 and at each end is confined in grooves 41 in the arms 37; thus the plate 35 has a horizontal movement when the 'arms 37 are moved with the rocking of the shaft 38. lVhen this movement occurs in a forward direction those reeds which are guided in the perforations 36l are moved forward in their notches 30a in the lower plate 31; and the upper or crank ends 2Ob of the reeds are respaced according to the spacing of the' open ends of the diagonal notches 34. With the plate 35 in the position shown in Fig. 6.all of the reeds are operative; as shown in Fig. 5 every fourth reed is inoperativevr and the remaining reeds are respaced to co-operate with the escapements of la magazine having a reduced number of channels. f

In order that the movement of the spacing plate 35 may occur automatically with the movement of they magazines, I provide as follows: To the shaft 38 is secured a pair of arms 42, to each of which is pivoted an arm 43. A stud 44 projects from each edge of those magazines having a reduced number of channels, and when the brackets D8 are returned to operative position following a magazine shift, the upper end of the arms 43 will ,contact with the studs 44, forcing the arms 43 downward and moving the plate`3'5 forward by reason of the connections described; The movement of the arm 43 is resisted by a spring 45, and if the magazine in operative position does kdoes not employ the studs 44 this `spring retains the4 arm in itsv upward position and all the reeds 20 remain operative. Y

Since the spacing of the lower ends of the reeds 2O is not changed when a keyboard having a reduced number of keys is inuse, it becomes necessary to provide other means for rendering `every fourth reed inoperative relative to such keyboard. This is accom.- plished by bending the keylevers 46y as shown in Fig. 7 so that they will engage only the operative reeds, each fourth reed remaining idle between adjoining key leviers. Fig. 6 shows all of the reeds operative -in connection with a keyboard having-,aimaitimum number of keys.

rIhe .escapements 33 are similar to those described in my co-pending application No. 139,721, in which certain magazineshave escapements and others have merely a perforation in the matrix channels, requiring a raised position of thevreeds 20. To accommodate this present invention to such an es- Y capement system, I provide asfollowsrA pair of levers 47 are secured centrally to a shaft 48 supported in the brackets D8. .These levers carry a shaft 49which supports the reeds 20. Arms 5() are pivoted to the levers 48 and those magazines which have the iescapements 33 omitted carry studs 51 which force. the arms 50- downward when the brackets D8 are returned to operative position with such a magazine in use. Thusthe levers 47 are rocked with the shaft 48 and the shaft 49 raises the reeds 2O through the openings (not shown) through thel magazine floor. When thus raised the reeds rest on a compensating elevation 52 on the key lovers 46, aslight manual movement of the tray 23 controllinw their position either in front of or above t ie elevation 52, this movement being insufhcient to clear the latch 25. The reeds are guided in a suitable notched or perforated plate 53 near their lower ends.

In said application Serial No. 139,721 it Y yis explained that the. escapements 33 are arranged in two alternating series for two sets of matricesin a single magazine. In order that the reeds 2O of lthis invention may co-operate with such van escapement system the guide plate 31 is arranged -to slide in the grooves 30 in facingsides of the bracket 138. A slight manual movement of this plate will place the reeds 20 in a selected fore or aft position relativeV to the esca-pe'- ments for the purpose stated. brackets I)8 are swung forward the plate 31 contacts with a stud 54and is forced to its rear position, this being the position it should occupy when the reeds are raised as hereinbefore explained when no escapements are employed.

Distributor system cmd its relationv tothe magazine system rma? keyboard systemj-The I/Vhen the distributor driving clutch (Figs. V and 12) is similar in-action to that of my PatentNo. 1,389,369.

of clutch members 57 which engage the hub of argear 58 which meshes with gearsgon'the with a projection '72 on the rod if the rod 67 is prevented from moving fordistributor screws for drivingV the same. `The clutch members 57 are held in, resilient engagement with the hub of the gear 58 `by means of a splitV ringl 59. In'the event of anV abnormal condition offering resistance to the distributor screws, lthe pulley55 continues to revolve and the clutch members 57 are thrown out of engagement with the hub of the gear 58, whereupon the spring 59 moves across the pivot points 60 of the members 57. The construction diers from that of said Patent No. `1,389,369 chieliy in the substitution of the split ring 59 for the -springs of `said patent. 1When the ring 59 isrthrown to the position showny in dotted lines (F ig. 12)4 by reason of an abnormal condition, it strikes and moves a swinging safety lock 62 pivoted in a bracket 61. The swinging end 62 ofthe lock 62 normally lies between the .bracket 61 and an opening 63 through a sliding bracket 64 which supports the shaft 65 upon which the clutch asa whole is supported. vEach time the keyboard tray 23 isswungforward `preliminary to shifting magazines the slide 64 is -moved rearwardly as a result 'of such movement of the keyboard tray. The connections fory causing such movement are a centrally pivoted lever 66,'and a rod 67 terminating beneath a vshoulder 68 on the. assembler-entrance channel Q. The movable vtray support yD9 carries a pawl 69 which engages a shoulder 70 onthe .rod 67 and isnormally heldin contact-with said shoulder by a Vspring 71 securedV at its opposite ends to the members 67 and D9. A stud 73 in the member D9 normally Vlies i behind and moves forward But ward long'ritudinallyV by reason of a fdistributor obst-ruction, then the'stud 7 3 forces the end of the rod 67 upwardlyagainst the shoulder 68 and the. keyboard tray cannot be moved a suflicient distance to permit the magazines to vbe freed for movement by the latch When an abnormal distributor condition exists the rod 67 cannot move forward because of the fact that the swing end 62 of the lock 62 has been throwny from in front of the opening 63 to the position shown in'dotted `lines in Fig. 12 and the slidebracket 64 is as av result locked against movement. It will be understood that the purposeA is to prevent a magazine shift while matrices remain on the distributor bar v74 vas the result of a distributor stop resulting in the split ring 59 being shifted in position. lt may also happen thatan attempt be made to shift magazines when the distributor is The pulley 55is provided withy a square hub 56 to which vare pivoted a pair` running normally but the matrices havey not been fully distributed. vF or such an event l provide asfollows: The distributor baris anchored by means of a bail 7 5 held in the upperends of the frame E; hence the distributor bar does not move with the slidebracket 64. As in my co-pending application Serial No, 139,7 21 the matrices enter opposed grooves 76 when dropping from'the ydistributor bar. Since the members in which these grooves are formed move with the bracket 64 while the distributor bar remains, the ribs separating the grooves 76 will strike the upper ears of any matrices traveling on the distributor bar when yan attempt is made to move the bracket 64 through the connections'explained, and as a result the magazines will remain locked against movement until the matrices have been fully distributed. Having thus describedmy invention and its mode of operation, what I claim as'new and desire tofsecure by Letters Patent,is:

1;'The combination, in a typographical machine having a distributor for matrices and a throat through which said matrices pass to'assembling position, of a column of matrix magazines differing one from another as to number of their matrix channels' according to'thickness and number of matrices intended to be accommodated therein, a
